Overview

Extended technology with SIMOTION
SIMOTION D Control Units support the coordinated motion
control of multiple drives. Technology objects are implemented
in addition to drive objects on these Control Units. These are
grouped to form technology packages and make available
extended motion control functions (e.g. synchronous operation,
cam disk, path interpolation and others) or technological func-
tions (e.g. a cam controller, a temperature or pressure control).
The IEC 61131-3-compliant PLC integrated in SIMOTION D
Control Units means that they are not just capable of controlling
sequences of motions, but the entire machine including HMI and
I/Os.
You can obtain further information about SIMOTION in the
Industry Mall and Catalog PM 21.
Comprehensive package of open-loop and closed-loop control functions
A wide variety of standard functions such as setpoint input, data
set changeover, controller optimization and kinetic buffering en-
sure a high degree of functional reliability and excellent flexibility
of application.

• Droop
• Brake control
Mixed operation with V/f con-
trol modes is possible; it is for
this reason that the V/f control
modes are stored only once in
the "Vector control" drive
object.
V/f is not possible for reluc-
tance motors.
Catalog D 81.1 provides
additional information about
reluctance motors
.
Position control can be
selected as a function module
from both the servo and vector
modes.
Synchronous motors (1FK and
1FT) and linear motors can be
operated only in Servo mode.
